you can put the 2j in tehre but its not much of bolt on like the 1jz is, teh motor is a little bit bigger and little bit heavier..so some extra modification can be done

What are the differences between the 7m and the 2jz motors?

I mean in the head and in the block its self. I see insane numbers pumping from the 2jz build, which is nifty, but I have a hard time finding information on the motor.

For the record, I'm pondering doing this swap for my car, when I find the right one.

If for nothing more then the parts availability. I can't find to many things for the 7m(internals and what not).

theyre pretty much totally different motors, the heads flow differently, the stock bottom ends are different...the only thing similar is that theyre both 3L, though its hard to believe u have a hard time finding info on teh 2jz.. its harder finding info for the 7m....

I seem to find consistant problems with getting technical information of either motor.

Materials used in construction, main journal sizes, so on so forth.

i normally search google or msn for info it gets me some info

WiseAssJester · 11-15-2005, 03:13 AM

Yeah, I'm looking again and again. Yahoo, Google specifically.

I found the bore and stroke, boost levels, compression levels, ect. A very informative site(http://www.jza70.com/articles/engine...omp_chart.html).

But nothing about materials used for construction. I'd imagine its an aluminum head, but don't know for sure. Are the pistons forged? What're the rods rated to? Valve sizes.

Haha. Thanks for answering, mang.
